Well, 42pi is the result of multiplying 42 by pi, isn't it? In the default MthIO mode the calculator strives to display as many results symbolically as possible.

To convert a single result to decimal, press SD. To have all results come out in decimal, press SHIFT MODE 2 to select the LineIO mode.

What formula do you use to calculate cylinder volumes

Volumes are any three dimensional measurement...

I Seriously doubt that I could get Pi ("pie") to print...
But I'll just GIVE YOU the number (much simpler)
Pi = 3.14159

Inches, feet, yards or meters.. all the dimensions need to be in the same values... So if you have an inch "ruler"...
That is just fine...!!

Your first step would be to determine the diameter of the inside of your cylinder in inches...
CONVERT that to the RADIUS by DIVIDING by 2...
Multiply that RADIUS by itself and then by 3.1416 = area of circle in INCHES... (radius "squared" x Pi = (square inched)

Then MULTIPLY the height (in inched) by the AREA...

But I'll just GIVE YOU a REFERENCE (much simpler)
mathematical constant ?
Area of circle

How many gallons does a 15' round pool 35 deep have

Basic school maths Pi R Squared, but are you sure this pool is 35 FEET deep?

Pi, (3.142) x radius squared
the radius is half the diameter x itself, x depth. and then

There are 7.48 gallons in cubic foot

Your pool diameter is 15' diameter, so 7.5 radius. 7.5 x 7.5 is 56.25. Multiply that by the depth. Multiply that answer by 7.48 gallons

It wont give me the value when i multiply like 6 x pi

Your calculator may be able to use the symbol Pi. If it gives you a result with Pi, you should convert it to a decimal approximation. There must be a key to convert.

I can get pi, but then when i need to multiply it by a number (example: 6), It just gives me that number, with the pi sign beside it. it wont give me an answer.

When in MathIO the calculator displays pi symbolically. If you want the numerical value of an expression, press [SHIFT][=], not just [=]. You can try pressing the [SD] key to toggle between fraction`/radical to decimal. You can also configure the calculator to use LineIO by default.

When i try to use the pi key with another operation it does not compute. For example if I am trying to multiply 10 times pi, the calculator reads 10pi

Press the FD (fraction to decimal) button after you calculate 10 times pi, This will give you the
calculation in decimal form.
